The 2015 Centers for Disease Control Sexually Transmitted Disease treatment guidelines currently recommend a single 2-g dose of oral metronidazole as the preferred regimen for treatment of trichomoniasis in human immunodeficiency virus (HIV)-negative women. Mounting recent evidence has shown that the 7-day oral metronidazole dosing regimen is more efficacious than the single 2-g dose. This commentary reviews the implications associated with these new data and discusses issues surrounding it that should be considered moving forward.

This commentary reviews the implications associated with new trichomonas treatment data in women, which suggests that all women should be treated with 7 days of oral metronidazole.
